Description

Technical Field

[0001] This utility model relates to the field of servo electric cylinder technology, specifically to a push rod type AC servo electric cylinder. Background Technology

[0002] Servo electric cylinders, as actuators, are key products in mechatronics and are widely used in various automated control systems, involving expertise in mechanics, motors, electronics, and computers. Current servo electric cylinders convert the rotational motion of a stepper servo motor into linear motion via gears or pulleys. This linear motion, driven by the motor shaft and coupling, then propels the servo cylinder's lead screw. However, this conversion efficiency is low, making it difficult to guarantee transmission precision, and the overall length is relatively long, occupying a significant amount of space.
